摘要：

We reanalyze precision LEP data and coupling constant unification in the minimal supersymmetric SU (5) model including the evolution of the gaugino masses. We derive general bounds on the primordial gaugino supersymmetry-breaking mass-scale m1/2 in terms of the various input parameters. The model cannot accommodate m1/2 < 1 TeV for values of alpha-3(m(Z)) < 0.115, even for extreme 1-sigma values of the other inputs. We emphasize the sensitivity of this type of calculations to the various input parameters.
